List - I | List - II |
|---|---|
(A) | (p) Liebermann's nitroso reaction |
(B) | (q) Evolution of with |
(C)
| (r) Dye test after diazotization |
(D)
| (s) Green colour with |
| (t) Carylamine test |
Options:
Answer:
Solution:
Question Explanation:
The question asks to match different classes of amines (primary aliphatic, primary aromatic, secondary aromatic, and tertiary aromatic) given in List-I with their characteristic chemical reactions/tests given in List-II .
Concept:
This question is based on Chemical Reactions of Amines, Distinguishing Tests for Primary, Secondary, and Tertiary Amines, Diazotization, Liebermann's Nitroso Reaction.
Solution:
(A) 1° alphatic amine with HNO2 gives alcohol and N2 and also gives carbyl amines test.
(A) → Q,T
(B) 1° aromatic amine gives dye test and also gives carbyl amines test.
(B) → R, T
(C) 2° aromatic gives N-nitroso compound with HNO2 , which gives Libermann's nitroso reaction.
(C) → P
(D) 3° aromatic amine on reaction with HNO2 gives p-nitroso compound which is green in colour.
(D) → S
Final Answer: (A) → Q,T ; (B) → R, T ; (C) → P ; (D) → S
